My lab went digital and we’ll never go back

John Batchelor: “I’ve been working digitally for about six or seven years. When we first got into it, I think the challenge for us was just the fear and learning new software. The first time that you see the computer screen and all the buttons… where do you start?

As a prosthetic and orthodontic lab, we were not used to digital workflows or investing in hardware. Whereas crown and bridge laboratories have traditionally, been quicker to adapt to digital and purchase equipment like, furnaces, mills …

For us, 3Shape and the software have been very good. The workflows are similarly designed to the analog ones that we are used to. You just need a different mindset.

Start basic

I think that like anything, your digital journey starts with a first step. And as a prosthetic lab, I think you need to start basic. You can begin with special trays, chrome partials and RPDs.

In our case, our biggest challenge was trying to stay focused. Because, you want to do so much. You get excited because you can now do RPDs splint design, dentures… But what we needed to do was slow down.

So, we ended up saying, OK, this is what we want to learn, RPDs. And then we’ll learn to design our special trays and then move on to designing digital dentures.

I believe that once you learn the basics, you can expand on what you want to achieve. You get used to the software and the workflows.

You can move on to doing full uppers, lowers, you can do copy dentures. We now do copy dentures, which I refer to as relines. Being able to do adjustments on an immediate denture is just such a big advantage with the digital workflow.

For our younger technicians and clinicians coming through, they were quick to adapt. It’s an evolution. I’ve been in dentistry for a number of years. I can remember plaster of Paris impressions. Then along came alginate… poly-ethers, gypsum, implants… digital is just the evolution of what we have always been doing.

But we found that by switching to a digital workflow, it has just made our lab so much more efficient in the way we operate. It’s also great for the environment, there’s less wastage. There are just so many plus sides. I would never go back.

Choosing hardware

Because we are a prosthetic and orthodontic lab, when it came to hardware, we naturally chose the (3Shape) D2000 (lab scanner) because it could scan upper and lower models all at once. So, for us, it was more of an orthodontic-based decision.

But I would say that with the launch of the E4 scanner, and the other E scanners, which are all very good scanners, that our prosthetics laboratories will consider an E4 scanner because they are so fast.

One of the things that we appreciate about 3Shape, as compared to the other programs that I have played around with, is the ongoing development of their software. They come out with major updates every year, so it’s very, very good program. And one that continues to improve.

I remember reading a 3Shape brochure back in 2012 that said, “the digital denture is coming soon.” Well once the software was able to record vertical dimensions, that’s when the lights went on. It became a reality and today, it’s really a good workflow.

With the new 2019 (Dental System) software we can now mill, instead of a mono block, we can mill from 3-7 or 4-4, 2-2, 1-1, so you can get a lot more out of your puck. It’s great for the environment, there’s less wastage. When we come to a patient with a large diastema, we can mill 2-2, 2-3, 2-8 on one side, and the same on the other side. We are saving on material costs and again, the environment.

From a clinician’s perspective, I think that the diagnostics with 3Shape software is fantastic. You might have a patient that has a delayed immediate, and you have forgotten vertical dimension or the bite, you can still construct a digital denture and they can take that home.

If you have a patient that has worn their posterior teeth or support and have gone from a class 1 to a class 3 and you want to rehabilitate that patient, you can quickly create digital dentures and send them home. For me, digital diagnostics has been excellent.

Being a hands-on technician, I don’t like to hear myself say that I will take a far better impression with a printed special tray than one I’ve crafted myself. But in the end, it’s about consistency. If you want a three-milled spacer, it’s uniformed. Whereas when we work in the analog world, the wets might be a bit firm.

And now with the developments going on in printing, digital is becoming even more cost effective. For example, you can print your work overnight. When I was at IDS, I saw so many good printers. There’s a lot of great technology out there now.

So if you are a lab doing RPDs, all you really need is the software and maybe a printer. And then you can work out to milling and printing it in a sinter: you don’t need all the equipment.

Printers are also more relevant than ever due to the tremendous growth of intraoral scanners. What we’ve noticed over the last six to eight months is that we are receiving quite a few scans from our KVRs, dentists, from in and around New Zealand. It’s really becoming the norm right now.

I think as technicians we need to remember, that a butterfly started off life as a caterpillar. When you go digital, you have to go back to being a caterpillar. Learn the basics, and then you can advance to becoming a butterfly.

With digital, you’ll be able to do what you do now, only much more efficiently. I would never go back.
